Description

The present invention relates to a medical bag used in the medical field and containing a liquid substance such as a nutrient solution, a drug solution, or an infusion solution.

In the medical field, liquids such as chemicals and infusions are used, and medical bags are used to handle such liquids. For example, in the enteral nutrition method in which a nutritional solution or a drug solution is administered to the stomach or the like through a tube inserted through the nasal cavity of a patient, a nutritional supplement supplement bag for storing a predetermined amount of the nutritional solution or the drug solution is used. ..

In such a medical bag, a storage area having an opening at the upper side is formed by fixing both side portions and lower side portions of two main body sheets generally made of soft synthetic resin.

By the way, when a medical bag is used, a work of pouring a liquid material such as a nutrient solution or a chemical solution into a storage area through an opening is performed. This injection operation is generally performed by one person, keeping the opening of the medical bag open with one hand and tilting the cup held by the other hand to contain the liquid contained in the cup. It is done by pouring into the area.

However, since the main body sheet constituting the medical bag is made of a soft synthetic resin, there is a problem that it is difficult to keep the opening constantly open when the liquid material is poured through the opening.

In view of such a problem, in Japanese Patent Application Laid-Open No. 2011-78737 (Patent Document 1), an opening / closing operation portion composed of a strip-shaped sheet is fixed to each outer surface of the two main body sheets to the outside of both main body sheets. A structure has been proposed in which both fingers inserted into each opening / closing operation unit are opened so as to be separated from each other by providing holes for inserting fingers in each of the above, so that the fingers can be held in an open state.

However, in Patent Document 1, the upper end portion and the lower end portion of the band-shaped opening / closing operation portion are merely fixed to the central portion in the width direction of the main body sheet. Therefore, the lower end of the opening / closing operation unit is located at the center of the main body sheet, and the external force associated with the opening / closing operation concentrates on the central part of one main body sheet, and the lower end of the band-shaped opening / closing operation unit. Since the central portion of the main body sheet portion is less likely to be locally deformed due to the sticking of the portions, there is a possibility that there is a problem in durability. In particular, when the opening / closing operation portion is fixed to the main body sheet by welding, there is a concern that the central portion of the main body sheet may be damaged or the strength may be reduced due to the welding process or variations in conditions.

Japanese Unexamined Patent Publication No. 2011-78737

The insertion holes 40 and 40 are to be inserted, and the insertion holes 40 include an insertion slit 36. In the present embodiment, since the insertion slit 36 is formed so as to straddle the plastic fastener 24 vertically, the insertion portion 38 is also provided so as to straddle the plastic fastener 24 vertically, and the insertion portion 38 is provided outside the plastic fastener 24. Is located.

Furthermore, in the present embodiment, the scale 42 is attached to the third sheet 32, and in particular, in the present embodiment, the scale 42 is printed on the outer surface of the third sheet 32. As a result, the amount of the liquid material contained in the storage area 12 can be visually grasped from the outside. However, such a scale 42 may be attached to the inner surface of the third sheet 32 in place of or in addition to the outer surface of the third sheet 32 as long as it can be visually recognized from the outside, and the first, second, and second scales 42 may be attached to the inner surface of the third sheet 32. It may be attached to the sheets 14, 16 and 34 of 4.

By the way, the manufacturing method of such a medical bag 10 is not limited in any way, but a specific example of the manufacturing method of the medical bag 10 will be described below.

First, the first sheet 14, the second sheet 16, the third sheet 32, the fourth sheet 34, and the like may be prepared in advance with a desired shape, but preferably with a predetermined width. The first, second, third, and fourth sheets 14, 16, 32, and 34 are prepared in a state in which a long resin sheet is rolled into a roll. Since it is possible to use the same members as the first, second, third and fourth sheets 14, 16, 32, 34, in such cases, the first, second, third and The same member is used as a member in which the fourth sheets 14, 16, 32, 34 are wound in a roll shape, and the third and fourth sheets 32, 34 are formed into the first and second sheets 14, 16. After fixing, the insertion slits 36, 36 and the scale 42 may be formed. Further, the ridges 24a and the concave grooves 24b constituting the plastic fastener 24 are also prepared in a state where a long object is wound in a reel shape in the same manner.

Then, with respect to the press welding area of the press welding apparatus for heat welding the resin sheet, the resin sheet of the first sheet 14, the resin sheet of the second sheet 16, and the resin sheet of the third sheet 32 , The resin sheet of the fourth sheet 34 is pulled out from the roll, and the sheets 14, 16, 32, 34 are introduced into the rolls, respectively. In the pre-processed area up to the press welding area, insertion slits 36, 36 are formed in the third and fourth sheets 32, 34, and the first to fourth sheets 14, 16, 32 are formed. , 34, the necessary printing such as the scale 42 is performed. In the present embodiment, the width direction dimension of the insertion slit 36 is substantially 0, but the insertion slit 36 may be opened with a predetermined width direction dimension.

Further, on the first and second sheets 14 and 16, in the fastener welding area as a preparation area up to the press welding area of both sheets 14 and 16, the ridges 24a and the concave grooves 24b constituting the plastic fastener 24 are formed. Each one of them is pulled out from the reel and superposed. Then, these ridges 24a and recessed grooves 24b are continuously welded to the resin sheet of the first sheet 14 and the resin sheet of the second sheet 16 in the length direction. As is known, such welding is performed on the resin sheet of the first sheet 14 and the resin of the second sheet 16 in the sheet-shaped portion 26 which projects from the ridges 24a and the concave grooves 24b on both sides in the width direction and is integrally provided. By continuously welding to the sheet in a straight line in the length direction, it is possible to avoid the thermal effect on the opening / closing function portion of the ridges 24a and the concave grooves 24b. The sheet-shaped portion 26 that projects from the ridges 24a and the concave grooves 24b on both sides in the width direction and is integrally provided is preferably formed of a sheet material having a relatively high deformation rigidity.

In this way, one of the ridges 24a and the concave groove 24b constituting the plastic fastener 24 is fixed to the overlapping surfaces in advance, and the resin sheet and the first sheet of the first sheet 14 introduced into the press welding area. The resin sheet of the second sheet 16 and the resin sheet of the third sheet 32 and the resin sheet of the fourth sheet 34 are overlapped with each other, and the upper side portion and the lower side portion of the medical bag 10 and the width direction The welding mold is pressed against both side portions and press-welded. As a result, the first sheet 14 and the third sheet 32, and the second sheet 16 and the fourth sheet 34 are welded on the four peripheral sides, while the first sheet 14 and the second sheet 16 are welded together. Means that the three peripheral sides excluding the upper side portion, which is the opening 22, are welded.

At that time, in order to avoid welding of the upper side portions of the first and second sheets 14 and 16, for example, a welding prevention sheet is sandwiched between the upper side portions of the first and second sheets 14 and 16. Press welding is performed at. Further, during this press welding, the ridges 24a and the concave grooves 24b located in the welded portion 28 are thermally deformed and crushed, and substantially disappear.

After that, the superposed sheet-shaped welded body sent out from the press welding area is introduced into the cutting area, and is punched and cut by the press cutter in the plane shape of the target medical bag 10. As a result, an upward opening that can be opened and closed by the plastic fastener 24 between the overlapping surfaces of the first and second sheets 14 and 16 in which both side portions and the lower side portions in the width direction are integrally fixed. A containment area 12 with 22 is formed. At the same time, the third sheet 32 and the fourth sheet 34 are superposed on the outer surfaces of the first sheet 14 and the second sheet 16 in a state where the surrounding four sides are fixed.

The formation of the insertion slit 36 in the third and fourth sheets 32 and 34 and the printing on the outer surface can be performed after the press welding step as described above. Further, as described above, the port member 30 is a welding type having a recess corresponding to the port member 30 in a state where the port member 30 is sandwiched between the first and second sheets 14 and 16 in the press welding step. By press welding using the above, the port member 30 can be welded at the same time as the press welding of the first to fourth sheets 14, 16, 32, 34. Alternatively, after welding the first to fourth sheets 14, 16, 32, 34 with only the fixed portion of the port member 30 left unwelded, the port member 30 is inserted and welded in another step. , It may be fixed by adhesion.

Although the manufacturing process of the medical bag 10 of the present embodiment has been illustrated above, it is not limitedly interpreted by the above-mentioned manufacturing process as described above. For example, the plastic fastener 24 is sent into the press welding area of the first sheet 14 and the second sheet 16 in a state where the ridges 24a and the concave grooves 24b are meshed (the plastic fastener 24 is closed). At the same time as press welding, it is also possible to weld to each of both sheets 14 and 16. Further, in the above description, the first to fourth sheets 14, 16, 32, and 34 are fixed by heat welding at the same time, but the fixing means is not limited to heat welding. Further, the first to fourth sheets 14, 16, 32, 34 do not need to be fixed at the same time, and for example, the first to fourth sheets 14, 16, 32, 34 may be fixed in sequence.

As shown in FIG. 4, the medical bag 10 of the present embodiment having the structure as described above is one of the insertion portions 38 provided on both the front and back sides (the first and second seats 14 and 16 sides). It can be gripped by inserting the fingers 44 into the insertion hole 40 from the side. Note that FIG. 4 shows a state in which the medical bag 10 is gripped with the left hand assuming a right-handed user, and is shown on the left side in FIG. 1 with respect to the front and back insertion portions 38 and 38 (FIG. 2). The finger 44 is inserted through the insertion hole 40 (on the right side of the inside), and the tip of the finger 44 protrudes from the insertion hole 40 on the opposite side, but in the case of a left-handed user, the finger 44 is inserted from the opposite direction. It may be put in. Further, in FIG. 4, the thumb is inserted into the insertion portion 38 provided on the front surface side (first sheet 14 side), and the thumb is inserted into the insertion portion 38 provided on the back surface side (second sheet 16 side). Although the state in which the four fingers 44 are inserted except for the above is shown, if the fingers 44 are inserted into the insertion portions 38 and 38 on both the front and back sides, they are inserted into the insertion portions 38 (insertion holes 40). The type and number of fingers that can be inserted are not limited.

With the fingers 44 inserted into the insertion portions 38, 38 on both the front and back sides in this way, the fingers 44 are separated from each other (the opening operation of the opening 22 is performed), so that the first sheet 14 and the first sheet 14 and the first sheet 14 are opened. The sheet 16 of 2 is separated from each other, and the opening 22 is more reliably held in the open state. As a result, the liquid material can be injected into the accommodation region 12 through the opening 22, and the liquid material can be administered into the body through the port member 30 and the catheter connected to the port member 30. When the fingers 44 inserted into the insertion portions 38 and 38 are separated from each other to open the opening 22, the meshing between the ridges 24a and the concave grooves 24b of the plastic fastener 24 is released in advance. It is desirable, but not limited.
